AbstractConvergenceChecker
@Deprecated public AbstractConvergenceChecker()
Deprecated.in 3.1 (to be removed in 4.0). Convergence thresholds are problem-dependent. As this class is intended for users who want to set their own convergence criterion instead of relying on an algorithm's default procedure, they should also set the thresholds appropriately (cf. MATH-798).Build an instance with default thresholds.

in interfaceConvergenceChecker<PAIR>
- Parameters:
iteration
- Current iteration.previous
- Best point in the previous iteration.current
- Best point in the current iteration.- Returns:
true
if the algorithm is considered to have converged.
